The trouble with GMail Talk, is that -- well, to put it bluntly, we all have a relative or "friend" who can be annoying. You can't take them off your GMail chat list in case they get upset, but every time you log in, you dread their appearance!!
Well you can log out of GMail chat and use Kopete instead. OK you can use a few others, too. Anyway, what I have found is that blanket invisibility doesn't work on Kopete with GMail But individual invisibility does. Right-click on the annoying relative's ID, and hover the mouse down to their gmail address at the bottom of the menu. On the sub-menu, select "Set Availability" and what you do, ONLY applies to that person. And it works. Or it seemed to.
A related point is that you can set up a "Windows Live" chat account without getting Hotmail. All you do is sign up using any email address you like. I had read something about them blocking Google stuff, but I was able to sign up using a googlemail (that's what we call it in the UK) account.
It was then a simple matter to track down my unfortunate M$ victim friends (I do try, really I do), and add them to my contacts on Kopete, and without any ado, they are available too.
Next time I see my gf, I'm going to update her computer (PCLinuxOS of course) and install Kopete. Get both her GMail and Hotmail accounts on it. I want to test the video link because currently she has aMSN and I cannot get the video link working with Kopete on my rig. So let's see what we can do!
At present, Kopete allows you to connect with:
AOL Instant Messenger, Bonjour, Gadu-Gadu, ICQ, Jabber (includes GMail), Novell GroupWise, QQ, SMS, Winpopup, Windows Live Messenger and Yahoo! Messenger
An add-on is being developed to allow you to handle Facebook chat through it.
Does this program know any limits?
