I asked Artjom if he would be able to revive an old WoW addon which needed updating. He was very quick and polite with responding to my request and even faster with making the required fix. The addon is working again and I am greatly appreciative of his knowledge and expertise in this field. Will definitely recommend and use again in the future, thanks!
