Just to keep short here: I've written a clone of columns in 1997, and I'm interested in hosting it now. So I want to ask: Should I post it somewhere in the web, or just ask abandonware sites host it for me?

abandonware sites will not tuch this with a half foot pole! (which is to say they will id you ask real nicely, but aren't eager to)
you could on reloaded, but there are generaly various sites (like http://www.upload.com/ if memory serves me right) which will host various c-p for newbie developers (free of charge naturaly).
hope I could be of assistance, don't hestitate ask if I missed anything out.

Whats wrong with a columns clone

I guerentee it would be good for reloaded since the site is about freeware and retro remakes!

you need:
1) quality revew
2) screenshots
3) and most importantly (I've done some remkes in my time- they sucked) we have to see that it's good quality (I'm not trying to offend you, but talented people are usualy on sourceforge, and you can arrange for a download there, so we have to chek. once again no offence implied)

Yes and you especcially need a link to this game

which is what he is asking us to arrange. (he doen't have it on the web). still I think he could have posted it on some free download site like I suggested.
