If you have been here for a couple of years your first thought might be to roll your eyes but someone who wants to offer an opinion could well feel trapped - don't resurrect an old thread or get flack for starting a debate already done one twice or more in the memory of long standing members
Generally 6 months will get the thread closed and last posts deleted. Don't worry about starting a new thread after a 6 month break.

There are some exceptions which I judge case by case, mostly dealing with non-controversial topics. Main reason necro posting is not allowed is that people have a hard time defending a position stated 3 years ago, or even 6 months.
