I would post Mergeto summary article notices on each article leave them a couple of weeks then where there is no objection just go ahead and merge into a summary article Only post articles to AfD that are trivial there is an objection to merge but there is no attempt to expand Group AfD s can run into problems when it turns out that one member of the group is in fact notable even if all the others are not Individual AfDs would flood the AfD And I thought some of the bi lateral relations stubs were trivial
