Create an offline copy of an online forum (Website copying)

Hi, There is an online forum called: https://educationforum.ipbhost.com/ The forum might be closing down soon and i would like to have an offline copy of the forum on my desktop computer in order to continue reading the threads after it closes down. The forum is not well covered by Archive.org I have tried using a website copying tool called "HTTrack Website Copier" but i cant get it to copy the forum. Would you be able to create a copy of the forum for me so that i could continue to read the various threads on the forum after it closes down? Thanks, Richard
