Hey ELG, first of all- Welcome to Qatar!
Damn!! Ronin beat me to all the info i wanted to give!! LOL!
But seriously I wonder why not many people know about/use the maps & timetable on that site...probably bcoz its hardly ever advertised?

Anyways I kinda agree with a lot of things said about travelling on the buses here, esp if u or a woman- no I havent done it, but I think 90% of the time you would get stared at...which IMO happens just about in any public place here...the chances of getting "felt up" are slim, but yeah, i suppose it could happen if u travel alone on a regualr basis...my guess if u do, then u probably are going to have some regular 'busmates' too??

besides i TOTALLY agree with Greeker, do not hesitate to raise your voice against the offender- "the buggers who try to act funny are also the scaredest people on the planet "- SO TRUE!
At the end of the day its all a matter of using ur discretion too- which i gather from your posts you are pretty good at- so I wont say any more ( wow, I have said so much already!)

Anyways as for calling the UK- i agree cheap calling would be some Voip service - try the ones suggested here, but also Do TRY MediaRing Talk- they are also a VOIP service offering Pc to Phone Calls, and they were offering Free calls sometime back- but I am not sure if the offer is still on- you might have to look it up...

Thats it from me...Hope you have a good time!
