-##GSOC teaser tasks
-
-####update Contacts last seen for muc messages as well
-The contact class (entities/Contact) has the ability to save the last time that Conversations
-  received a message from that contact. Currently this time only gets updated for one-on-one
-  messages. In non-anonymous mucs messages from a contact should also update the last seen
-  time.
-
-####Select multiple Contact in Choose Contact Activity
-Currently the choose Contact activity allows only for one contact to be selected. A long
-press on one contact should bring the activity in a mode where the user can select multiple
-contacts.
-The Activity should then return an array of contacts instead of just one
-
-####Request and respond to message receipts in MUC PNs
-Private MUC messages either dont request message receipts or dont respond to them. The source
-of error should be determined and eliminated. A rather small tasks that just teaches you a bit
-about the stanza parser and generator in Conversations
-
-####Edit dynamic tags / groups
-The context menu for the contact list (StartConversationActivity) should offer the ability to
-edit groups. (Any UI decissions are left to you) Quick suggestion though: Dialog with
-checkboxes for existing groups and some way to enter new tags.
