I think we all make typos, but it doesn't personally bother me much. I can easily correct it in LOG4OM and then, once in a while (e.g. once a month), I can manually upload new (and delete existing) log in Clublog. Doing it this way is easier (less time consuming) than having to upload manually every QSO or even having to do it manually just once a day or once a week.
