To improve the looking for a group system, on the creation of a campaign we could have a combobox with a list of the most played rpg systems, so when I’m looking for a group i can select on a combobox and search for campaign’s with that system specifically. Obs: I know that the system used in a campaign can be specified on the campaign name, When I search for a D&D 4, D&D 4.0 or D&D 4e for example in most of the cases it won’t find any game although if i type D&D and manually search for a D&D 4 game I will find plenty of them. Maybe the primary cause for this issue is the freedom of typing the system name as you wish within the campaign's name, so when I search for a D&D 4 it won’t find the games that have D&D 4e, if I find any D&D 4 game at all.
