stability does seem to be the main concern. I found a yahoo server - netlab.cz which works pretty well.
Not 100% happy with the AIM server the Ursine one.
But - all in all, i have been up i'd say 80% of the time. which is better than webmessanger was - at least a year or so ago.
hard to complain. Besides, i always consider IM secondary to email as far as a contact. so its mroe like a bonus.
And i keep ramble on the handheld as a backup.
But the handheld integration is just fantastic
- and, i find is much more stable if i leave it logged on, with a desktop
luckly i have 2 ready to serve the purpose
