Installed FCKeditor into Serendipity. The main problem that I am trying to solve is the irritating page break problem (with HTMLarea) that drives me nut.
In the process of doing that, I found a way to create soft link to FCKeditor, so that I do not need to install multiple copies of the editor. I guess this method works only with IX WebHosting, it allows me to delete the soft link through FTP even though httpd is the owner of the soft link. Another point to note is, the full path needs to be specified when creating a soft link.
