I agree that “Talk to @bob. Tell him where to go.” should not include the . in the tag. But “Register @dynalist.io” would be nice to include the punctuation. Also would be nice to have #x/y do tag groups where x is a group, and y a subtag of x.
@Kenneth_Aar@Rene_Molenaar: we relaxed the limitation so that as long as the tag is not in the form of "#tag. " (note the same), it will work. So if you have a character after the dot, the tags will continue working.
