We're all hoping so. There's a lot of Doctor Who fan fiction writers and this way the pressure to write an entire script or story is off and plus you get people you never expected chiming in.
I am going to be strict on admin though and delete really stupid or inappropriate unfunny crap.
Having taken a look, many of the story-lines seem to require a better memory of past stories on the show than I now retain, but I hope to contribute here and there. This is possibly not the best time of year to be starting a venture like this, though; most addventures that I've been involved with seem to have a big dip in activity during the ummer months.
The Doctor Never-Ending Adventure isn't as aimless as the other ones seems to be, it's a fan fiction tool so we figure there will be some high output people going through, no idea about the summer thing, guess we'll see. It can just sit there and wait until people jump in.
