How hard would it be to implement this for only certain usergroups eg, paid members?

Was waiting for this.. but seems like it has a lot of bugs right now.

Not too hard, I might work on it myself. Set it so VIP groups can use it etc.. or X group(s)

Mate if you would be kind enough to forward me the code you placed to restrict groups I would greatly appreciate it.

The Mod appears to be working very well, notifications work nicely. However very important people follow darthos posts about amending the code slightly.

Well I haven't tried it out fully. But, I will play with it this weekend and see how it goes and let you know.

Hmm would

Work efficiently if so where should that go in the XML?

Well what I am thinking of doing is adding a section in acp, so you can select which usergroups can use this hack.

Ahhh if only I was that good with coding!

I'll wait for you then :)

From what I can tell it will put just a little bit more stress on the server compared to posting a new reply. Just because it's going to check if the post is quoted and then create a notification.

OK Should be OK then for only Premium Members I guess! Lookin forward to your usergroup mod now even more ;)
