List of bugs that I've found and fixes that have worked for me (running google chrome) just in case others are having the same problem.
Can't log into instant messenger - Log out of Gaia, then log back in again
Keep getting logged out then into messenger - You may have too many tabs open, close some then wait a little while, that may fix it. If that doesn't do it, try closing completely out of gaia for a couple seconds to a minute or two, then opening gaia back up again. <--- It looks like the maximum number of tabs is three or four.
Status disappears when logging out of either instant messenger or gaia - I'm not sure if this is a glitch or intended, and I don't really have a fix for it. Just thought it'd be worth mentioning.
Footer not loading - It looks like this is affecting the safari browser of the ipod touch as well as firefox four. I don't really know of a fix for this yet, but I'm trying to think of one for my itouch. The only thing I can suggest right now is downloading google chrome, firefox (preferably not version 4), internet explorer, one of the more widely used browsers. At least until it's fixed. Before deciding that it's a problem with your browser, however, go into your account preferences and make sure you have the footer display set to yes.
Are your tektek forum icons appearing all over the place in your post? - This is a result of the new instant messenger, if you want to fix this, simply deactivate the widget from the labs page. I've tested this myself and it solves the issue.
Your friends are shown online in Gaia, but not on the instant messenger? - They simply haven't enabled the new floating footer yet, try encouraging them to do so if you really want to chat with them this way :'D
This list will be updated :3
