During summer, I somehow managed to collect huge backlog on Gammu. This consisted on few hundredths of emails to reply, bug reports, not reviewed records in phone database and so on. Today I can finally say this is mostly over and I should be able to react more quickly. Though this does not change anything on previous statements about limiting my involvement there.
Processing emails went quite smoothly, luckily some of them resolved themselves or others have helped on mailing list. With bug reports it is more troublesome, because there are topic which I don't want to touch and thus looking for volunteers to work on that. Maintaining Gammu packages in Ubuntu PPA so that users would be able to install latest version easily is one of such tasks, which are waiting for somebody.
Anyway I feel much better without those unread emails and I hope not to collect so huge pile of them again :-).
