I am developing a little web application and i want to have a rudimentary commenting system. This has turned into an academic exercise
I want a user the ability to reply to a comment which itself may be a reply.
The comments table would be something like
replyTo (null if top ancestor an existing id if a reply)
So for example the following structure may be a snapshot
Because of the recursiveness of the comments i cannot think of how i can get an ordered system which i then then just dump to a div with an indentation to imply the level.

Can anybody help me pls in how to get an ordered recordset using Mysql (if it is possible even ). I am stumped
There may be a restriction say of 3 levels say if that is any help ie there can be a reply to a reply, but not a reply to a reply to a reply
They would be chronologically-ordered in reverse (by ancestral comment) and maybe by priority of ancestral comment.
I ave implemented a similar system using a comment table and a replies table and just merged the two.
I was basically wondering if it were possible to use a single table and have any nested level.
