The meeting of Lansdale Borough Council started out on a somber note last night.   Officials there took a moment to remember long time Reporter Newspaper employee Lynn Janoff.   She faithfully attended council meetings for years before losing a battle with cancer last Saturday at the age of 62.   Janoff was a community volunteer.   She worked tirelessly for the Lansdale Public Library.   She was a member of the First Friday Committee too and gave her time freely at the International Spring Festival.   She also supported many non-profit groups including the Robin Hood Foundation and Community Housing Services.
