Hello everyone -- Nice to see some renewed activity on HWE of late. Keeping fingers crossed that it continues and also that some of the many (hundreds of) lurkers here will be lured out of hiding to post to the list. (Hope springs eternal....) Remember, no one here knows who you are and what your research is all about unless you tell us. Nor can anyone offer you advice, support and possible help. And now would also seem as good a time as any to remind everyone about our list guidelines. Three of them in particular, actually. First, please capitalise all surnames you mention in your posts, including in the subject line. This is the simplest, most effective way to draw other people's attention to those surnames. Second, when you reply to a previous post, it is only necessary to include brief snippets of that previous post -- as necessary, for clarity -- in your reply. It is completely unnecessary to include the entire previous post. So please delete it before sending your post to the list. Third, when replying to previous posts, change your subject line if the topic of the thread has changed and the original subject line no longer applies to what you are saying. For those of you who are new here and possibly wondering about our list guidelines, stay tuned for my next post, coming up right after this one. Andrea (HWE list concierge)
