Hello @lama10!
I noticed you have posted many times since you began your journey on Steemit. That is great! We love active partipants.
I do want to point out that the Introduceyourself tag is meant to be used once only to introduce yourself to the Steemit community. You have now posted 5 times using the introduceyourself tag. Please see this link for more information on Tag Spam?
Please take this into consideration and help build a great platform!
