I think a post like this would get more replies if it was in the regular part of this section of the forum as opposed to the visitor part of class discussions. Ask a mod to move it for you or maybe just make a new topic here http://forums.warppo...me-discussions/ (the main part, which is below the sub-forums) or even here http://forums.warppo...community-chat/
It sounds like you last played Rose before it went evo. I'm pretty new here too- came from another server that was classic Rose so I can sympathize with your confusion on what to do and where to start. It would be impossible to give a "brief" summary of changes that have happened over several years but reading topics here at the forum really helped me and my friends start to understand everything better. There is a lot of information here if you look around. You can always pm one of the class representatives for the jobs you are wondering about. Here is a link to the list of those people http://forums.warppo...out-your-class/ One important thing if you plan to make a fs cleric- charm is more important than int when it comes to strong buffs. Yes, I did say charm 
You didn't mention which server you are on but if you're on Draconis, feel free to add me in-game ign HoneyBuns. I'd be glad to share my limited knowledge with you. Please don't be discouraged. This community is very friendly and helpful. I think some old time players are just a bit preoccupied atm with some recent changes in the trading system so don't be upset that no one replied to you yet. I am really enjoying playing here, and I hope you will too. Just have an open mind to learning a new way to play Rose and you will do fine.
Gotta head to bed now- it's late here. See you ^^
