If you are really interested in the topic you translated you can talk about the things brought up in there in your next posts and also give a link to that post with a translation. Interlining different topics and posts is good for forum if they are informative and useful. It's not what I do on everyday basis, but it happens regulary when I link to some of my previous topics or posts if there is some additional info or interesting discussion connected to what is actual in ongoing thread.
Don't let your work get buried if you are really interested in it and suppose it important and informative.

I don't know about interest, but I, myself, learned a lot thanks to those translations. In my first translation, I didn't knew what BBcodes were. As my translation finished, I learned the basic use of BBcodes. You would be laughing after hearing this. I thought Bbcodes were some kind of HTML keywords.
The first topic was related to KYC and CEX, where some thief stole a person's identity. Then there was another topic about "Help bitcoin help Ukraine". I knew there was an ongoing war. But I didn't knew any details. After translation, I realized how cruel Putin really was. There was another interesting topic about PGP. It really got me. A senior user also made an additional post regarding this. He made a whole guide in our local thread about how to use PGP. Lastly, there was this famous topic, "The Silkroad Case." I'm sure you've heard of it.
I don't know about others, I don't know if anyone read my translation. But I benefited a lot from them. Recently, I made a complete list of all the translations that I and (Learn Bitcoin) brother did. But unfortunately, it also got buried.
Yeah, I'll keep that in mind. I'll re-post everything again when we get our own local board. Until then, I will have to quote it and keep the topic alive.
