Ok I realised what you meant by "homepage" @Cleoriff, I think you mean the list of different boards (those blue tiles with links to the boards) that was visible on the previous homepage. I see a few of you are asking about the boards. On this new homepage, the way to navigate around the forum is a bit different. It might take some time to get used to. Here are a few tips that I hope will help, for also your question @jonsie around how to post a new topic in a specific section:
3 quick links below your latest posts (or the welcome / sign in slot if you're logged out):
- From the middle link "Explore the forum", you can get to a topic in Welcome & News where we have listed all the boards.
When you're in a thread:
- you can use the "breadcrumb" links at the top of the thread to get to the relevant board or category of boards.
On the homepage:
- When you scroll down to the Community Topics, you can see a button for "Ask a question. This brings you to the page where you can post a new topic on the board you choose.
The breadcrumb links I mentioned above look like this on top of threads:
Thanks @Cleoriff, we've captured your comment around the missing number of PMs next to the Messages link!

Can we have the list of forums back please.
Click on Explore the forum....
Hi everyone, thanks for the comments so far @Cleoriff, @gmarkj, @jezza1234, @Bambino, @jonsie, @Poppysmum, @sheepdog, @liggerz87, @MI5! Having gone through these, there seems to be a few common themes we can spot, just letting you know we've captured these and would like to discuss more soon. 
- Top O2 menu, specifically the sign-in link, has created some confusion when trying to login directly to the community instead of My O2
- The top image feels very big across all community pages and requires more scrolling
- Lack of a number specifying how many unread PMs you have in the top "Messages" link
- List of categories on the homepage to navigate directly to discussion boards. It's definitely a big change that it's no longer visible as direct links, a new way of navigating around the forum on this new version - it seems that you are missing the previous structure and it would be great to hear more around how you were using it before and what specifically you miss about the old one so we understand a bit better?
Please do keep the feedback coming, and apart from these that have already been mentioned, do you have any comments around the general feel of the page compared to the old homepage?
To add also, I've just edited in a brief description in the list of new features above relating to the Notifications feed. That's something we didn't have earlier so please do try it out also when you get a moment.
Cheers everyone
Is it just me or does "here are all your latest posts" meant to say "here are your started topics"?
Screenshot:
@Marjo its the fact that you got to the main page and knew exactly where you wanted to go. Simple! At the moment the new look is not engaging me to click anywhere of interest other than what is (forced) suggested.
Is that a design decision to put the "popular searches" in the middle of the page rather than the logical place of just below the actual search bar? Its orphaned where it is now and has no real context for the user.
Is there any need for search a large sized icons for the "activity" section. Seems to be a bit of a contradition in that there's 2.4 million members and only 25 solved problems (as if its like some of us come on here only to talk about Dancing on Ice 
)
Exactly what I thought when I looked at 'My Latest Posts'. It should say 'Started Topics'
(personally I have no interest in seeing a page of topics I've started!!).
The nice arched image is a little on the large side, consuming much screen real-estate on a laptop (landscape) vs the mobile view (portrait on a smartphone). Could it be trimmed down a touch, perhaps?
Also the "Unread Posts" *still" defaults not to "Discussions" view but to the view with every response showing with a "Re:..." on it.
And to add pictures on a smartphone you still have to go into "Full" view from "Mobile" view.
Seems to e a common thread here 
Oh, and I asked the moderator to move my "Look, a new forum layout" thread into this thread - that should rattle a few bugs or two! 
And the timestamps are an hour out in the two different views (posted at 07:28 as shown in the first image):
And an hour later as shown in the new homepage:
