I'm running now 4.11 and I'm quite happy. However, I did get my hands on new box: IBM x230 with 2X1gig intel 6x.X.SCSI.X.33.6 and 3 gig of ram. My old server is basicaly a web server with cgi and php, hosting my own web sites. I would like to upgrade the whole thing. Which way to go? 5.5? 6.1 or just stick with the 4.11 thanks regards wlodek
