Is there any way that we could make the ENI Forum registration Universal? Like you register at one board but you have membership of all the boards??

i doubt that'd be possible without combining both boards, tho i know Powerglide all about php it might be possible to combine the databases.

It is possible but its a big security risk. It would also require a certalised db admin team among all the sites involved. And all those people selected would have to be highly trusted by all parties involved. Aside from that its a Blotload of work to do and isn't worthwhile unless these sites are cash cows, which they aren't.
