Hmm, well no joy at present getting it to work outside the forum pages, and I had to reset the system/reinstall it after fiddling around with the source code :(

Other than that, works great and my users love it! Now all I need is something built on this to integrate it into our premium features that allows one to have more than one account >>

Also, perhaps some way of viewing all accounts that are mapped at all in this system.

Thanks for this nice hack!
Suggestion: Only certain group(s) can use this feature

Does this script lay a cookie entitled "userid"?

No.

Anthony,

Great mod, but can you please add a feature for only certain groups to be able to access this function?

I simply enclosed the whole modification to the USERCP template with:
and:
Now only users from the groups 2, 6 and 7 will see the hack in UserCP.

Anyone got it working on Vb3.64?

This works on 3.6.4. 3.6.0 is the minimum version required in the 3.6.x series.

This only seems to work with 'primary' usergroups, either that or it doesn't work for a more than three numbers in an array?

I have users awarded a usergroup as their secondary usergroups, and want the ability to link available to them then.

Please use is_member_of($bbuserinfo, 2, 6, 7) in the conditional instead of what he posted.
