Translation of Glühlampe

I will be visiting in Italy from April 10 to 15 in order to meet some old friends. I'd like you to attend a one-day course, maybe I can help you in learning something new. Please give it a try.
Maybe we would need to say install our dictionary as a software? But I would say instead of install, use our dictionary as a software. So bottom line. If I use the singular form for newsletters and websites, I am on the safe side for both?
No matter then. I wanted to study Spanish for years now, because you know, it really helps? And how long have you been learning Spanish? Please write me soon. Best wishes. Your Alfi.
