well, LGSL does what it should, ok, maybe the protocols are a bit out of date (like missing MW3/BF3 support) but LGSL is not broken thus it doesnt need an urgent update. for the missing protocols, there are topics including code to just copy/paste.
a search feature was never the plan probably. i think LGSL was not ment to host a sort of long tracker list like game-monitor or gametracker does.
regarding security, i've done some search for LGSL exploits but so far i could only find one but this one seems to be a hole by a 3rd party (it's an issue with the now dead CMS "DaFun Spirit") and probably not an issue with LGSL itself. so no updates required there either.
if the day comes that LGSL breaks on something and Perry isn't around i'm surely willing to look for a fix. But there are quiet some active people out there using and modding LGSL so i'd be surprised if none of them would in this case help to figure out a fix. SpiffyTek
