I haven't heard anything but have been moving my groups over to groups.io
without any problems. Yahoo had a hiccup in their login for a bit and I couldn't move my bigger groups over then there were many problems (again) at Yahoo with accessing and posting to groups.
finally got through Yahoo!'S mess and I am transferring the last of my groups over, good riddance to Yahoo! It will take a couple weeks to get everything transferred over.
I personally don't like the way Googlegroups are setup (for one thing, you do not receive your own emails back if you send a message to the group and there is no way to change that).
I'd say; if you are thinking of moving- go for it while you can!
Ohh crap.... PAT.... ?
Seems to be a comment going around on other groups that Yahoo is closing
groups in a few days (24th).
Anybody working on the move to Goggle yet?
