I was looking at this code and considering if a more compact solution was possible.
I don't particularly like variables with a number on the end, they don't make for easy code reading.
Linq doesn't always make for easier reading either, but it is a bit less code.
Getting the lower case versions into the wordformsToUpdate could be done similar to the following (I haven't checked if this compiles).

  wf => {
    var otherForm = wf.Form.VernacularDefaultWritingSystem;
    return otherForm != null && form != otherForm && !string.IsNullOrEmpty(wf.Text) && cf.ToLower(otherForm.Text) == form.Text;
}

But that still leaves the issue of knowing if we should add a call to the idlequeue.
I guess we could check if we have changed the wordformsToUpdate count by checking the size at the beginning and end of the case statement...
What do you think?

Code quote:

					foreach (IWfiWordform wordform2 in uniqueWordforms)
					{
						var form2 = wordform2.Form.VernacularDefaultWritingSystem;
						if (form2 != form && form2 != null && !string.IsNullOrEmpty(form2.Text))
						{
							string sLower = cf.ToLower(form2.Text);
							if (sLower == form.Text)
							{
								m_wordformsToUpdate.Add(wordform2);
								m_mediator.IdleQueue.Add(IdleQueuePriority.High, PostponedUpdateWordforms);
							}
						}
					}

I don't know anything about Linq. There could be more than one uppercase wordform (e.g. titlecase, uppercase, camelcase). I would be happy to rename wordform2 to ucWordform and form2 to ucForm to make the code clearer.
