BuddyPress.org

Hi all,
I’m new to Buddypress and it looks like a great component. I only struggle to adapt the description of the groups. The editor is super basic and it doesn’t really allow to adapt the description. What I want to do is different groups per region where people can put in a map a spot where they want to meet up, e.g. here for the city of Freiburg: Freiburg Gruppe
So basically I’d like people to put in a description of the group and then based on their location there should be an iframe for Google Maps) integrated.

Can someone help or provide a hint on how to embedd an iframe and adapt the description a bit?
Thanks all in advance,
Anna
