I was looking at the battlestar-galactica tag and noticed that it seems to define two additional tags for the expansions, namely "battlestar-galactica-pegasus" and "battlestar-galactica-exodus". Neither tag has any entries. However, there are two questions tagged exodus. I attempted to edit those questions so that their tag was "battlestar-galactica-exodus", but encountered an error:
Oops! Your edit couldn't be submitted because:
'battlestar-galactica-exodus' exceeds maximum tag length of 25 characters
What should we do about this? Maybe switch to "bsg-exodus"? But that seems less clear...
