Found this little info

Have always loved to see both Star Trek and Doctor Who do a joint venture (currently trying to come up with such revolving all series:
Enterprise-7th Dr
STO-4th Dr
Next Generation-6th Dr
DS9-8th Dr
Voyager-5th Dr
updated movies-9-11th Drs)

But any way, started me thinking, what actors appeared in both shows-below is a link to find that out-most of all check out the updated movie-that will throw ya for a loop most of
all.

Any who wishes to help etc about the twin shows please yodel

I haven't watched Doctor Who, but I'd love a canonical Trek/another sci-fi series crossover. A BSG crossover would be particularly easy to make, as it could happen either through time travel (the shows could easily take place in the very same universe) or the head people.

^ He's put the smiley in the link code, here is the link to the MA article: (http://memory-alpha.org/wiki/Doctor_Who

Trekbbs has a fan fiction section, which is where this belongs if you want to see if anyone wants to write this with you. I'm sure there will be one or two people who visit that section who have already combined Trek with Who in a story.

Oh, and I'm guessing you mean TOS not STO.
