When chooses user "Full Profile" option, gateway should get information from gadu-gadu server and fill details.
Out of curiousity, what XMPP chat client are you using? =) (has no bearing on this, I'm just curious)
Related to the actual issue – this is tied into the "full vcard support" issue. I don't currently have a timeframe on that but I'll certainly look at it. I would like to see this for ICQ so I could handle both at the same time. I might aim to get this in for 1.1.4 depending on how much is going on. =)
