May I hi-jack this post? dooBdoo you helped me post my signature a while back and I need your help one more time. Actually I have everything written down as to what I have to do. I am planning on changing the sig and I have a concern as to how to save the existing one.
I went so far as to type it in the sig box but the existing one still shows, after clicking on the save button do I hit deplete and start typing my new sig? You have been so gracious in the past and to this day I do appreciate your help. The last time I posted with you, you were not doing well, hoping you are now in a good place. You are one of the kindest posters on these boards, always a pleasure to see you here. 
Hi, @Lindsays Grandma! Thank you for the lovely compliments and the good wishes. You are so kind, and you lift my spirits.❤️
Am I understanding that you want to save your existing signature in case you want to use it again later? I'd suggest that you copy it and then paste it somewhere like an email message to yourself, or a notepad or other area on your computer where you write and save text.
Then delete everything in the signature area in your settings so you can completely remove the current signature, and enter the new one and click "SAVE."
Hope that makes sense! Just give a shout if you have more questions and I'll try to help -- or if I'm not here I know another poster will help out. I hope you and your family are well. Thank you, again, for your thoughtful posts.
