Adding new store item / action

Hopefully somebody on here can help out with this...

Looking to add a new item to the store "Change other users Avatar"

How would I go about inputting this? And also, make it so they need to link a url avatar, so they cannot upload avatars to my server because I have it set so they can for their own but don't want them uploading a bunch of avatars when theyre changing them.

Any other store items that you guys have added and worked good on your forums?

Thanks

You might be able to change anothers avatar to one of your defaults, that might be the best and least obtrusive way of handling this.

Thats what I was also thinking... much better idea.

Would anybody happen to know how to do this?

IIRC the next version of ushop will have the basic change other user avatar function built into it but I haven't been keeping up so you may want to double check.
