How can a newbie help you ask?
Everyone, every one can use words of encouragement. A pat on the back. A cheer, a hug, a smile, a little levity. Let the new members know we are here for emotional support as well as having cost saving ideas and a broad range of knowledge of many aspects of cat health.
For example, you said you have some experience with pancreatitis. Use your own experience to help others that have cats with pancreatitis. Let people know we are here to help and encourage them to ask questions. Follow up your posts, to ask how things are going. That can get a dialogue going. If you don't know something, say so and PM someone to come take a look.
If you see an emergency situation, raise a red flag and let us know. There are so many posts, it takes time to get around to reading them all and hours may have passed. Yell for help if you need to. That 911 icon is for health emergencies, use it as such.
Tell people of your experiences in dealing with your sugarkitty. Remember the ECID. Let people know this gets easier, they will develop a routine. Yes, there are scary parts, but there is a special bond you develop with your cat.
Keep it short and sweet. Make it clear and understandable, use paragraphs and spacing for readability and clarify any abbreviations you use, like BG (blood glucose).
Be yourself. Let your joy in your cat shine through what you say. Keep it positive and upbeat.
If you don't think you can help, move on to someone else.
