The best Irish on-line resource for all things brewing is: http://www.irishcraftbrewer.com/, or try the newer version: http://www.beoir.org/. Unlike other boards, these guys are free of spammers, or spammers are immediately obvious, the administrators have a genuine interest in brewing and are neutral and you will get the real deal on homebrewing. Its an active community of brewers where everybody kinda knows everybody else. And they have a "Market Square", which allows individuals and suppliers to post offerings and exchange goods etc.
http://www.jimsbeerkit.co.uk is a UK "equivalent" and a great resource for info on all things brewing. They too have a "Bargain Bucket", and the admins are also refreshingly neutral, so you will get real info here too. Its just bigger!
