Hi, welcome and don't panic! If you have something to say on the subject of a thread absolutely go ahead and post a comment. You have as much right to say what you think as the rest of us
If you have questions about syn values or are looking for a recipe then there are special sub-forums to do that. Oh and as some questions come up time and again it's worthwhile doing a search to see if your question has already been asked and answered. I can't tell you how many time people ask about mullerlights, mugshots and pasta 'n' sauce
