Καλωσορίζουμε το Transfermarkt.gr!

what is the point of
https://www.transfermarkt.gr/market-value-analysis-greece/detail/forum/888

Here Greek speakers can discuss the market values of the SL1 and SL2. You can suggest values and it is advisable to argue well. Similar to how we do it here in German, but in Greek.

And please post rumors in the other thread. (They shouldn't be old either!).

I don't think there is a point of creating a whole separate forum with all the players for current rumors.
You probably have less than 10 rumors in 1 year and for only 5 players or so.
Now there are 57 pages with all the players that exist. This will change in less than 3 months. Every team changes more than 10 players every few months. I don't think it is sustainable and manageable.
I would advise to change it just to propose market values and not rumors.
Can you find rumors for more than 10 players? Very hard.

As for the "They shouldn't be old either" would only make sense if the player made worse appearances. For example about Ioannidis, the rumor was from May about 10 Mil. The player since then has better appearances, so the value should be higher than the old rumor.
