Hi vancouv,
Are you using Netscape? Unfortunately, since the revamp of Pprune's bulletin board software, it doesn't work in Netscape - you should have no problems if you use Internet Explorer... (assuming you're on a PC running Windoze, of course... if you're not, I guess Pprune doesn't want you any more!)
I was a fairly pi$$ed off about this myself, being a Netscape fan, but have been forced into using IE for Pprune, although I still use Netscape for every other site.
Interestingly, the HTML produced by the new BB software includes the 'nowrap' attribute in the <td> tags - IE seems to ignore this while Netscape faithfully honours it, thus knackering the display and making it about a million pixels wide!
