[sldev] Re: A patch to allow creation of megaprims from within the viewer

[Thomas Grimshaw]

Since it seems like this is being patched out of the system...

" [11:05] Gaius Goodliffe: Are you guys aware that the constraints that 
used to stop people from making new megaprims are gone?
[...]
[11:06] Andrew Linden: Yes Gaius, I heard about that. Kelly Linden fixed 
it -- should go out in the next server update.
[11:06] Gaius Goodliffe: Ah okay. :)
[11:07] Phli Foxchase: so, it's an exploit ?
[11:07] Andrew Linden: Yes, that 'feature" was really a bug and was 
unintended"

Is there any chance we could get a comment from a linden regarding when 
we can expect to see support for larger prims? Since i think everyone 
agrees it's something that is extremely useful and important.
