I was wondering. Since the MLP pools all have MLP in it so it can be searched or avoided, why not do it to other jonrah based pools?

Putting Sonic, digimon or pokemon in the name of a pool containing characters from these show. Original by pools that are not based on something that already exists and so on. Just a though.

I don't see why not, objections?

Sounds good to me as well, especially if it lets everyone know what they're getting into before clicking

On a related note, it looks like there are quite a bit of pools that are missing the artist/series-origin (in the case of fan-made comics) in their title

Since there doesn't seem to be any set format for listing them, what do you all think would be an effective idea?

Well you could always just use the inpool:true with mlp, sonic or any other tag for that matter.
