I completely agree with you that leaving solutions of top-rated coders is very important. Removing all solutions would mean losing a more-than 15 years history, that is criminally irreversible loss.

Lets hope they will not remove solutions from web.

I've been contacted by somebody to "not let this happen". I can talk to TC admins about this, of course, but first I need to understand your concerns (i.e., why this announcement caused so much panic).

First, this affects only about practice rooms, not the submissions done in the actual competitions. Such submissions are and will be available from the web as a "study resource for beginners".

Second, this is not the first time such cleanup is done, so there's no way this can cause "losing 15 years history"! In fact, I've found another announcement about practice rooms cleanup, dating back as far as March 2015 (which, by the way, caused zero reaction from the community), so we're talking about deleting at most 6 months worth of practice solutions.

Protip: save everything locally, all the time. You never know when shit happens and something's lost (see CF Black Day). Storage of text files is quite cheap these days.

I'm not sure if it's time to panic, though. I remember a previous "clearing of practice rooms"; AFAIK, my submitted solutions remained. What exactly is being cleared?

But I'm going to save my solutions just to make sure.
