Your English is better than that of many Americans is, probably because you actually try. No worries.
I found the timeout for edits. It is 3000 minutes, or about two days.
Since what you are doing is removing and then reposting, I have decided not to change it.
The forum has a rule against "bumping" topics. Meaning, posting useless content like "bump" to bring it back to the top.
This is to support the integrity and value of the forum, at large, by only having meaningful posts.
Between you and I tho, we can all agree that a lot of posts are not really "meaningful".
I would request that you not remove and replace threads for less-popular models. Instead, perhaps try a google search and then post any new results you find. If no new results, perhaps post that you have just done a search and have found no new content, inquiring if anyone else has.
