- I can type really fast, so I can offer you express services without additional costs.
Sorry, just don't brag about something unless it is really worth bragging. Some people spend hours on their posts. Much longer posts, maybe with in-depth research, and made in fancy formatting..... oh, pro tip: Long post is for when you have a lot to say. Short post is for when you don't. Length is not good or bad in itself!
Maybe I haven't understood your post well, or maybe you didn't understand mine, but what I meant in this post you searched for in the archive is that I can finish translations of long documents in a short time. This kind of services are usually more expensive (express translations), but as I can type really fast, I don't charge more for this kind of works.
I hope you now understand the point of the "brag" and why it was worth mentioning it.
