Decision on Community Server
After going back and forth on making a decision, I finally decided that I will stick to my existing code base. I really enjoy coding and did not want to take away the fun in coding my own solution as opposed to using a ready made solution. I know I would be reinventing the wheel, but that's what weekend coding is for.
The biggest change that I am planning on the site is moving the existing code of saving blog entries to XML file to saving them to a database. This is especially required since I have asked a couple of good friends of mine to enter their own blog entries here. File locking would simply kill the enthusiasm.
I am already through with the database schema and business logic and am currently testing the solution. Basically I have 3 tables Categories (used simply to tag blog entries), BlogEntries (stores all the blog entries entered by various authors) and Comments (any feedback received on a blog entry). Once I am done with testing, I have to migrate existing XML file entries to the database (this is going to be fun).
