Some accounts in this community and others are currently whitewalling. (i.e: when you try to log in, you see a blank white screen)
If this is happening to your account, please try browsing while logged out, this should enable you to view the (public) boards.
The Yuku techs continue to work on this problem and apologise for the frustration and inconvenience it has caused you 
Yuku suggest you should be able to access via the forum levels at some communities that are currently whitewalling. (e.g. click on one of your recent posts to access the forums and use the forum jump menu to go from one forum to another)
Unfortunately, this isn't a guarantee of working
The problem lies with the Yuku server and the techs are doing their best to try and fix it.
Also those of you who use Internet Explorer 8
If you are having problems with posting pictures, using smilies etc with either posts or your signature, (as I was ) you may need to switch to Compatibility View . The
developers will be making Yuku compatible with IE8, but until then, you may need to use Compatibility View. You will find that in your Task bar.
Pippa told me this before Yuku did 
and 
again
Internet Explorer 8 is a new release and some websites may not yet be ready for Internet Explorer 8.
