Anyway, to combine my own servers.ini with a new version from the mIRC site, I do this - I copy my ini file to Word, convert it into table, cut the column with numbers, do the same with the updated servers.ini file, copy both files together, sort their lines, remove all duplicate lines and then number all remaining lines. Then I save this merged to a new servers.ini. It's very tedious, though, and there should be a normal way of doing this - like a command "Import new servers" or "Merge servers.ini with a new file" in the mIRC menu. 6.04?
