lot of work to be done on these pages so thanks for the help The main microorganism page is almost embarrassingly sparse if you had some time to expand it that would be great By the way if you are going to edit more science articles in the future you will find this tool very useful it creates formatted references from PubMed ID numbers Saves you a lot of time All the best No problem I m always glad for a bit of extra help with out of the way subjects Thanks again for your help with this if you have time could you read through my expanded version of the genetics section and see if this is too technical for a general reader
