first of all my apologies for a so direct object.
Lichess site is wonderful but it has a tool that i like much more than other things:it is study tool.
Instead to open a post or blog on an online page,you can create chapters with study tool here on lichess. So my questions are:
are studies that i create infinite in time(i mean,if i no delete them,they resist in the time)?Lichess will remain always free?
Thanks for answers!
