Thanks for these sharp comments!

You're welcome.

Can I come back on this page to add new comments if I need help to implement it or to get some value?

You would be most welcome to.

There is so much topics posted each day that I assume it is difficult to check if there is a new comment for an old node (except if you look carefully the newest nodes section)

The simple answer is to become a member! It costs nothing, take maybe 1 minute to do, and then each time you log in, the server will show you a message telling you if you have any replies to any of your posts. It's so easy, there really is no reason not to.

Alternatively, if you really can't or don't want to become a member, the when you post a node (especially a top-level (new) question) make a note it's number. In this case it's 456165. Then, the next time you check back, type that number into the search box at the top left corner of the screen and click the button, and you will be taken directly to the root node and you can scan down for any new replies.

But really. Join! You are missing out on some of the nidest bits of PM by not doing so. For example, when you look at Newest Nodes as an Anonymous Monk, you get to see the last 24 hrs worth, but if you are a member, it only shows you those that you haven't already read (or decided don't interest you).
