Need my fix...

My gmail/gtalk seem to be broken.
I am unsure if this is them being crap or work blocking access.
Therefor, can anyone recommend a web-based chat client for gtalk - I can't install anything at work so needs to be web client please.

~Edit~
I'm leaning towards my account being broken from teh google end.
Email not coming in or going out it seems.
And I can't log into chat through imo either. Though that could be a blanket work thing, if they decided to roll it out at about 10.30am...

I feel my sanity slipping away with my lack of contact :)
